' STOVE-DOOR CONSTRUCTION.

Application filed November To all whom it -ma3 cancer-n: I

Be it known that we, LEWIS MOORE and CLAUDE DIBBLE, citizens of the United States, residing in Joliet, in the county of WVill and State of Illinois, have invented a new and useful Improvement in Stove-Door Constructions, of which the following is a specification. y This invention relates to a stove-construc- 1 tion and has more particular reference to the provision of an improved oven and broiler door and door frame for gas and other fuel stoves. A principal object of the invention is the provision of a flush closing stove door,

which will not require the outward extension of hinge parts and which will permitthe entire face of theoven and broiler to be in substantially a single plane except for the projection of the door handle.

Another and highly important object of ne invention is the attainment of this re-.

ult in a door swinging down .to and up from a-horizontal position, the while maintaining the pivot edge of the door out of contact ,but closely adjacent to .the'adjacent surface of the door frame, this arrangement preventing the marring of the finish through manipulation of the door and at the same time eliminating any substantial opening between the door edge and door frame when the door is in lowered position.

Another object of theinvention is the im-i provement of certain details of construction of the stove door andattendantparts as will be readily apparent from the following description. W

. Another important object of the invention is the provision of a stove door adapted to move down in an outwardly horizontal position when open, the'construction and arra ngement of which readily lends itself to accurate counterbalance. Numerous other objects and advantages better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof. L I

On'the drawings, Figure 1 /2 1s a front elevation of a stove front equipped with oven andbroiler doors of the invention will be apparent as it is 19, 1923. Serial No. 675,461.

spectively substantially on the lines 5-5,-

66, 77, and 8-8 of Fig; 2.

For the purpose of illustrating the invention we have shown on the drawings various views of an oven and broiler front equipped with our inventiom'only such parts of the oven being shown in section as is necessary to an understanding ofthe invention.

Referring to Fig. 1, reference'cha-racter -11 indicates the 'door frame, reference character 12 the oven door, and reference character 13 the broiler door. 3 it will be observed that in this preferred embodiment of the invention the parts of Referring to Fig.

the stove, exceptthe door handles 14 which may have any usual or preferred construction, are flush and lie 'in substantially a single plane, the door closing completely into the frame itself. The door frame does or may consist of a single sheet of metal stamped or cast to provide main frame portions 15 slightly rounded-to improve the appearance and having inset flanges 16 surrounding the door opening. The material of the door frame is depressed near the hottom of each ddor and at the sides at 17 to receive partsfof the door, as will be, presently' explained.

The stove doors 12 and 13 consist of body or main members presenting flat outerfaces and having extensions 18 adapted to'engag'e v .in and fit into the depressions 17 in the frame. The doorframe is slotted at 19 in each depression 17 to receive door lugs 21 extending inwardly from the rear of the extensions 18 "near. the-bottoms of the doors. Each of these lugs has a. curved,

surface 22 adapted torest upon the material at the'bottom of the recess which forms a ledge edge over which the lug moves in the opening and closing of the door. The,

lugs are so formed that they may be threaded through these recesses and each has at its top a Shoulder 23 adapted to engage back of the door frame above the recess when the door is in full open position to support it,

The invention contemplates the swinging down of each door from a closed position to an open one with the edge of the door adjacent a pivotal axis maintained close to and accurately out of contact with the curved surface 24 of the door frame adjacent thereto. To accomplish this the door in the present instance is slid outwardly slightly as it swings down about its pivot. This sliding and pivotal movement is controlled by a curved surface 25 on the inner ends of each lug which engages a leaf spring or friction reducing leaf 26 fixed on a curved arm 27 fast at 28 on the rear of the door frame just above the recess through which the lug moves.

Each door is counterbalanced by a spring. Reference character 31 indicates the spring for the upper door and this is connected at 32,. with one of the lugs 21 and also with a lug 33 on the door frame below the recessthrough which the lug 21 fast to the spring is arranged.

The broiler door is counterbalanced by a .yoke 41 having its arms arranged on opposite sides of one of the lower lugs 21. A headed pin 42 is thrust through aligned openings in the lug and yoke arms and a cotter pin 43 is positioned through an outwardly extending shoulder 44 beyond the head of the pin to prevent outward movement of the pin 42. The oke 411 extends upwajrdly back of the door ame andis embraced by the spring 45 bearing against a lug 46 on the inner side of the door frame through which a stem 47 of slidably engaged.

ach door'is provided with an" opening 51 (for the broiler door) and 52, (for the oven door) and into these openings suitable panels are arranged. These panels may be the yoke is mere opaque plate (as indicated at 53 in f the broiler door) or glass (as indicated at 54L in the oven door), the arrangement preferably being an opaque plate in the -broiler door and a glass plate in the upper one.

In the present instance we have shown a thermometer 61 arranged between two halfpanesof glass 5 l,the half-panes being engaged in channel members 62 at their meeting edgesand having companion recesses The glass for receiving the thermometer. plates and thermometer may be considered a single unit and this unit and the opaque plate below are secured in position by an inner plate or backing member 71 having lugs 72 adapted to enter into keepers ,73 formed along the bottom edge of the-door and having a laterally movin slide 74 at the opposite edge, this slide having de ressed tongues 75 adapted to enter under t rough I 75 from a keeper 76. As shown in Fig. 8

the thermometer is provided with front and back flanges 7 Sand 79 for engaging on the opposite faces of the glass parts 54.

The top plate of the stove, indicated by reference character 81, is attached to the front or door frame without-the fastening means being visible from without the stove, thereby improving the appearance of the top of the stove and giving a flush top surface. The top is provided with downwardly extending side flanges 82 arranged within side walls 83 bolted thereto at '84 at appropriate locations. These flanges are cut away at the front to abut against the inner edge of the door. frame and therebeyond .the top wall is bent down at 85 tobring it under the top surface of the top wall part and throu h the nut 89 upon the upper surface of the lug to force the top member of the stove into holding engagement with the flange 86 of the door frame.

Claims drawn to the wall construction and the construction of the oven itself, originally made in this application, are cancelled out for the purposeof filing a} divisional application. It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment there- 0-.
